Eaton FPATS Stand-Alone Fire Pump Automatic Transfer Switch

The Eaton FPATS is a stand-alone, fire-pump-rated automatic transfer switch. It transfers an electric fire pump from its normal power source to a standby or alternate source when the normal supply drops or is lost, then automatically retransfers once normal power is restored. FPATS is used with a separate fire pump controller, where the transfer switch and controller are individually listed. Every FPATS is built to order, so we quote each one to your horsepower, voltage, enclosure and options. Call (786) 336-5783 or send us your catalog number or spec section.

How the FPATS works

The FPATS transfers from normal to alternate power when the normal source drops below 85% of nominal voltage, or when any phase is lost or reversed. Its transfer mechanisms are mechanically and electrically interlocked, so the normal and alternate sources can never be connected at the same time. When the normal source's voltage and frequency return within pickup setpoints, the switch automatically retransfers. FPATS is designed for NFPA 20 Arrangement II installations, where a fire pump controller and a power transfer switch are individually listed.

Note: FPATS stand-alone transfer switches do not carry FM approval. If your project requires FM-approved equipment with transfer switch, see the FT series controllers, such as the FT30, which combine the controller and transfer switch in one FM-approved assembly.

ATC-300 Plus controller

FPATS is operated by Eaton's ATC-300 Plus, a panel-mounted, microprocessor-based controller that monitors both power sources and runs the transfer switch through programmed sensing and timing functions.

• Monitors source 1 and source 2 voltage and frequency, with undervoltage monitoring on both sources
• Five status LEDs: source 1 available, source 1 connected, source 2 available, source 2 connected, and unit status
• Seven-button keypad for programming, with setpoints stored in non-volatile memory
• Displays real-time and historical information, with a help/lamp test function
• Engine test button to test the generator, with a selectable run time of 0–600 minutes, plus an alarm silence pushbutton
• Alarm relay for conditions including improper circuit breaker operation, motor operator failure, lockout, failsafe condition, aborted engine test and aborted plant exerciser
• Time delay bypass for TDNE and TDEN

Enclosure and standards

• Enclosure: NEMA 2 standard, finished in fire pump red, with bottom cable entry; other enclosures available
• Standards: built to NFPA 20 and meets or exceeds UL, cUL and CSA requirements, New York City building code and U.B.C./C.B.C. seismic requirements. Does not carry FM approval. See the bid submittal for the full list of approvals.
• Large HP: large horsepower versions are available; see the Large HP bid submittal below

FPATS catalog numbers explained

For example, FPATS-60-D-L1-E1 is a 60 HP, 480V/60Hz stand-alone transfer switch with English labels in a NEMA 3R raintight enclosure.

FPATS or an FT series controller?

Choose FPATS when the transfer switch needs to be separate from the fire pump controller, for example when pairing it with a stand-alone FD30, FD60, FD70, FD80 or FD90 controller. Where one combined, FM-approved assembly is preferred, the FT series integrates the controller and a fire-pump-rated transfer switch. See all fire pump controllers with transfer switch.

What we need for a quote
